Hi Johann,
Unfortunately Anoop et al. are out for a few days, so I'm desperately
trying to understand and fix this before 8.1 :-(

Updated in my local copy (thanks) - unfortunately not a fix to the bug
reported by Marko.
I have narrowed it down some more though - it's not so much a colwise
issue, as a bind issue. You can see it with the following:
1) Set cache size to 2 and enable Declare/Fetch
2) Connect
3) SQLExecDirect "SELECT relname FROM pg_class"
4) Bind to column 1
5) SQLFetch
6) SQLFetch
7) SQLFetch *bang* :-)
I'm largely unfamiliar with this part of the code so any help would be
appreciated. FWIW, the bug seems to be libpq version specific - it's
certainly not in 07.xx.
Regards, dave
